Incidence and predictors of intraoperative hypotension during transurethral bladder tumor resection with oral 5-aminolevulinic acid.	OBJECTIVES: To analyze the incidence and risk factors of intraoperative hypotension related to photodynamic diagnosis-assisted transurethral resection of bladder tumor (PDD-TURBT) with oral 5-aminolevulinic acid (5-ALA). METHODS: We retrospectively analyzed 487 patients with bladder tumors who underwent PDD-TURBT (n = 184) or conventional TURBT (conv-TURBT) (n = 303) between 2018 and 2021. Intraoperative hypotension was defined as hypotension requiring vasopressors during TURBT, and its incidence was compared between the two groups. Potential risk factors of intraoperative hypotension, including preoperative change in mean arterial pressure (MAP), were further investigated in patients receiving PDD-TURBT. RESULTS: The median age was 72 years, 392 patients (81%) were male, and 203 (42%) had hypertension. TURBT was performed under general and spinal anesthesia in 76 (16%) and 411 (84%) patients, respectively. The incidence of intraoperative hypotension was significantly higher in PDD-TURBT compared to conv-TURBT (43% vs. 17%, respectively). The median change in MAP until the induction of anesthesia was +6.5 mmHg (range: -29.0 to +46.3) in the PDD-TURBT group and +14.7 mmHg (range: -35.3 to +67.7) in the conv-TURBT group, showing a significantly smaller increase in the PDD-TURBT group (p < 0.001). In the multivariable analysis for PDD-TURBT patients, advanced age, general anesthesia, and lower MAP change (<+6.5 mmHg) until anesthesia induction were significantly associated with intraoperative hypotension (p = 0.0104, <0.001, and <0.001, respectively). CONCLUSIONS: Intraoperative hypotension occurred more frequently in patients who underwent PDD-TURBT than in those who underwent conv-TURBT. Using oral 5-ALA decreases preoperative blood pressure elevation and may be responsible for intraoperative hypotension.	bladder
Young population bladder neoplasms.	OBJECTIVE: Bladder urothelial carcinoma is a rare condition that primarily affects the elderly and is rare in people under 40 years of age. There is no definitive information about the prognosis and clinical behavior of bladder cancer in young individuals. In our study, we aimed to investigate the prognosis and clinicopathological features of bladder tumors in patients under 40. PATIENTS AND METHODS: A retrospective analysis was performed on patients diagnosed with urothelial neoplasia who underwent bladder surgery between January 2008 and December 2020. The patient's medical records in our cancer database were collected. The study included stage, grade, multifocality, smoking habits, recurrence, and survival. The cases were divided into two groups: those under 40 (Group 1) and those over 40 (Group 2). The clinical and pathological features of young and old patients were compared. RESULTS: 17 patients (14 men and 3 women) under 40 were identified. The age ranged between 19 and 40, and the average was 30.6. One infiltrating urothelial carcinoma (pT1), twelve papillary urothelial carcinomas (pTa), two papillary urothelial neoplasias with low malignant potential, and two urothelial papillomas were all identified by pathology. Dysuria was the primary symptom that initially manifested. Recurrence occurred in two of 12 patients with low-grade papillary urothelial carcinoma in the young patient group. In a similar group of patients over 40, recurrence was detected in 7 out of 10 patients. Patients with urothelial carcinoma under the age of 40 have been noted to have single, small tumors, unlike older patients. No tumor progression was detected in young patients. All young patients are still alive and have not experienced any recurrences. In the group of older patients, tumor progression was observed in 11 patients (16.4%). CONCLUSIONS: Patients under 40 typically have low-grade and low-stage bladder urothelial cancer. Because urothelial tumors in young people frequently have a good prognosis and seldom recur, transurethral excision is the preferred treatment method for bladder tumors.	bladder
Geriatric assessment-derived deficit accumulation and patient-reported treatment burden in older adults with bladder cancer.	"BACKGROUND: When a person's workload of healthcare exceeds their resources, they experience treatment burden. At the intersection of cancer and aging, little is known about treatment burden. We evaluated the association between a geriatric assessment-derived Deficit Accumulation Index (DAI) and patient-reported treatment burden in older adults with early-stage, non-muscle-invasive bladder cancer (NMIBC). METHODS: We conducted a cross-sectional survey of older adults with NMIBC (≥65 years). We calculated DAI using the Cancer and Aging Research Group's geriatric assessment and measured urinary symptoms using the Urogenital Distress Inventory-6 (UDI-6). The primary outcome was Treatment Burden Questionnaire (TBQ) score. A negative binomial regression with LASSO penalty was used to model TBQ. We further conducted qualitative thematic content analysis of responses to an open-ended survey question (""What has been your Greatest Challenge in managing medical care for your bladder cancer"") and created a joint display with illustrative quotes by DAI category. RESULTS: Among 119 patients, mean age was 78.9 years (SD 7) of whom 56.3% were robust, 30.3% pre-frail, and 13.4% frail. In the multivariable model, DAI and UDI-6 were significantly associated with TBQ. Individuals with DAI above the median (>0.18) had TBQ scores 1.94 times greater than those below (adjusted IRR 1.94, 95% CI 1.33-2.82). Individuals with UDI-6 greater than the median (25) had TBQ scores 1.7 times greater than those below (adjusted IRR 1.70, 95% CI 1.16-2.49). The top 5 themes in the Greatest Challenge question responses were cancer treatments (22.2%), cancer worry (19.2%), urination bother (18.2%), self-management (18.2%), and appointment time (11.1%). CONCLUSIONS: DAI and worsening urinary symptoms were associated with higher treatment burden in older adults with NMIBC. These data highlight the need for a holistic approach that reconciles the burden from aging-related conditions with that resulting from cancer treatment."	bladder
The impact of second transurethral resection on survival outcomes in patients with non-muscle-invasive bladder cancer treated with bacillus Calmette-Guérin therapy.	OBJECTIVE: Several guidelines recommended that second transurethral resection should be performed in patients with diagnosis of high-risk non-muscle-invasive bladder cancer. However, therapeutic benefits of second transurethral resection before bacillus Calmette-Guérin intravesical instillation were conflicting amongst previous studies. We investigated the prognostic impact of second transurethral resection before bacillus Calmette-Guérin instillation in high-risk non-muscle-invasive bladder cancer patients. METHODS: This retrospective study included 3104 non-muscle-invasive bladder cancer patients who received bacillus Calmette-Guérin instillations between 2000 and 2019 at 31 collaborative institutions. Univariate and multivariate Cox proportional hazards models were used to assess the risk factors of intravesical recurrence, disease progression, cancer-specific mortality and overall mortality. RESULTS: In the entire population, patients undergoing second transurethral resection (33%, 1026/3104) had a lower risk of intravesical recurrence on univariate analysis (hazard ratio 0.85, 95% confidence interval 0.73-0.98, P = 0.027), although it did not remain significant on multivariate analysis (hazard ratio 0.90, 95% confidence interval 0.76-1.07, P = 0.24). Subgroup analysis revealed that, in pT1 patients (n = 1487), second transurethral resection was significantly correlated with a lower risk of intravesical recurrence on multivariate analysis (hazard ratio 0.80, 95% confidence interval 0.64-1.00, P = 0.048), but lower risks of disease progression (hazard ratio 0.75, 95% confidence interval 0.56-1.00, P = 0.049), cancer-specific mortality (hazard ratio 0.54, 95% confidence interval 0.35-0.85, P = 0.007) and overall mortality (hazard ratio 0.73, 95% confidence interval 0.55-0.97, P = 0.027) on univariate analysis. CONCLUSIONS: Second transurethral resection confers accurate pathological staging and could be used to safely select good candidates for intravesical bacillus Calmette-Guérin instillation. We further confirm that second transurethral resection could confer an oncological benefit in pT1 bladder cancer patients treated by bacillus Calmette-Guérin instillation, and so strongly recommend second transurethral resection in this patient population.	bladder
Optimizing outcomes for high-risk, non-muscle-invasive bladder cancer: The evolving role of PD-(L)1 inhibition.	Transurethral resection of bladder tumor followed by intravesical Bacillus Calmette-Guérin (BCG) is the standard of care in high-risk, non-muscle-invasive bladder cancer (NMIBC). Although many patients respond, recurrence and progression are common. In addition, patients may be unable to receive induction + maintenance due to intolerance or supply issues. Therefore, alternative treatment options are urgently required. Programmed cell death (ligand) 1 (PD-[L]1) inhibitors show clinical benefit in phase 1/2 trials in BCG-unresponsive NMIBC patients. This review presents the status of PD-(L)1 inhibition in high-risk NMIBC and discusses future directions. PubMed and Google scholar were searched for articles relating to NMIBC immunotherapy and ClinicalTrials.gov for planned and ongoing clinical trials. Preclinical and early clinical studies show that BCG upregulates PD-L1 expression in bladder cancer cells and, when combined with a PD-(L)1 inhibitor, a potent antitumor response is activated. Based on this mechanism, several PD-(L)1 inhibitors are in phase 3 trials in BCG-naïve, high-risk NMIBC in combination with BCG. Whereas PD-(L)1 inhibitors are well characterized in patients with advanced malignancies, the impact of immune-related adverse events (irAE) on the benefit/risk ratio in NMIBC should be determined. Alternative routes to intravenous administration, like subcutaneous and intravesical administration, may facilitate adherence and access. The outcomes of combination of PD-(L)1 inhibitors and BCG in NMIBC are highly anticipated. There will be a need to address treatment resources, optimal management of irAEs and education and training related to use of this therapy in clinical practice.	bladder
Optimal interval timing between transurethral resection of bladder tumors and Bacillus Calmette-Guerin perfusion.	OBJECTIVE: There is no consensus regarding the best interval time between transurethral resection of a bladder tumor and Bacillus Calmette-Guerin (BCG) perfusion. This study was to explore whether the interval time has an impact on the prognosis and adverse effects. METHODS: We retrospectively reviewed the clinical data of patients who received BCG intravesical perfusion at Sun Yat-sen University Cancer Center (SYSUCC) from September 2015 to October 2021. Recurrence-free survival (RFS) and progression-free survival were the primary endpoints. Cox regression was used to explore independent predictors. The association between interval time and adverse effect grade was detected by logistic regression. Propensity score matching (PSM) was performed. RESULTS: A total of 403 patients were enrolled, the median interval time was 24 days (6-163 days), and the follow-up was 28 months (7-82 months). Eighty-eight (20.9%) patients relapsed, and 40 patients (10.0%) suffered progression. The multivariate Cox regression analysis confirmed that interval time was an independent predictor of RFS (p = 0.017). Notably, when the interval time was less than or equal to 26 days, there was a trend toward better RFS, PSM resulted in 65 matched pairs in each group, and Kaplan-Meier analysis showed that there was a significant difference in RFS between groups (p = 0.009). The logistic regression analysis showed that there was no correlation between interval time and adverse effects and their grades (p > 0.05). CONCLUSIONS: We considered that the first BCG perfusion could be performed within 2-4 weeks after surgery.	bladder
Chitinase 3-like-1 Expression in the Microenvironment Is Associated with Neutrophil Infiltration in Bladder Cancer.	Bladder cancer is a common cancer with well-established therapeutic strategies. However, recurrence occurs in 50% of patients with non-muscle-invasive bladder cancer, and 20% of patients progress to muscle-invasive bladder cancer. The 5-year survival rate for muscle-invasive bladder cancer patients is disappointingly low, ranging from 36% to 48%. A molecular marker of interest is chitinase 3-like-1 (CHI3L1), which is elevated in various cancers, including bladder cancer. In addition to its role in cancer cells, CHI3L1 also has regulatory abilities in immune cells. Neutrophil infiltration has been shown to positively correlate with overall survival, progression-free survival, and relapse-free survival in bladder cancer patients. However, the relationship between CHI3L1 and neutrophils remain poorly understood. Therefore, this study investigated the relationship between CHI3L1 level and protumor neutrophil infiltration in bladder cancer. We analyzed the GSE128959 dataset and the data of a bladder cancer cohort undergoing chemotherapy. We observed higher expression of CHI3L1 in bladder cancer patients with invasive or chemotherapy-resistance. Our results revealed a positive correlation between CHI3L1 expression and protumor neutrophil infiltration. Elevated CHI3L1 expression was associated with genes which were related to the recruitment and infiltration of neutrophils. Consequently, CHI3L1 may serve as a novel evaluation factor for the degree of neutrophil infiltration in advanced bladder cancer in those scheduled for chemotherapy.	bladder

Pelvic lymphadenectomy: Evaluating nodal stage migration and will rogers effect in bladder cancer.	"INTRODUCTION: Pelvic lymphadenectomy (PLND) alongside radical cystectomy (RC), provides crucial diagnostic and therapeutic value in patients with bladder cancer. With the advent of neoadjuvant chemotherapy and prospective data supporting standard PLND, controversy remains regarding the optimal PLND extent and patient selection. Nearly 40% of patients may not receive adequate PLND, even though 25% of patients have positive lymph nodes (LN) at time of RC. We hypothesized that PLND still remains an important facet of bladder cancer treatment. To clarify the prognostic importance of nodal yield, we performed a retrospective investigation of a heterogenous population (pTanyNx/0M0) of patients undergoing RC. METHODS: From the Surveillance, Epidemiology, and End Results (SEER) program, we identified pTanyNx/0M0 bladder cancer patients undergoing RC from 2004 to 2015. Kaplan Meier curves and Cox proportional hazards models assessed cancer-specific survival. Patients were analyzed with PLND performed as the primary covariate. Survival analysis then stratified patients undergoing PLND by LN yield, both as a continuous and categorial variable (≤10, 11-20, 21-30, and >30), and T stage. RESULTS: The final cohort included pTanyNx/0M0 patients with urothelial bladder cancer (n = 12,096); median follow up was 39 (IQR: 17-77) months. PLND was performed in 81.45% of patients with a median LN yield of 14 (IQR: 7-23). Most commonly, patients had T2 disease (44.68%). After controlling for age and T stage, patients receiving PLND had improved CSS (HR = 0.56, [95% CI: 0.51-0.62]) compared to those that did not receive PLND. When grouping patients by LN yield, survival improved in a ""dose dependent"" manner (>30 LN: HR = 0.76, [95% CI: 0.66-0.87]). We noted similar results when stratifying patients into non-muscle-invasive (NMIBC) and muscle-invasive bladder cancer (MIBC). CONCLUSIONS: In a large contemporary series of pTanyNx/0M0 bladder cancer patients, we found a significant oncologic benefit to PLND. Higher LN yield correlated to improved CSS in non-muscle-invasive and muscle-invasive disease. Our data support the possibility of occult micrometastasis even in non-muscle-invasive disease. Additionally, in light of recent advances in adjuvant immunotherapy, our results emphasize the importance of adequate nodal yield for accurate staging and optimal treatment."	bladder
A phase I study of the combination of atezolizumab, tiragolumab, and stereotactic body radiation therapy in patients with metastatic multiorgan cancer.	BACKGROUND: Immunotherapy targeting the PD-1/PD-L1 pathway is a standard of care in a number of metastatic malignancies, but less than a fifth of patients are expected to respond to ICIs (Immune Checkpoint Inhibitors). In a clinical trial, combining the anti-TIGIT (T cell immunoreceptor with Ig and ITIM domains) Mab (monoclonal antibody) tiragolumab with atezolizumab improved outcomes in non-small cell lung cancer. In preclinical models, SBRT (Stereotactic Body Radiation Therapy) could increase expression levels of the inhibitory co-receptors TIGIT and PD-L1. We aim to assess the combination of tiragolumab with atezolizumab and SBRT in metastatic, previously treated by ICIs, non-small cell lung cancer, head and neck cancer, bladder cancer, and renal cell cancer. METHODS: This phase I study (ClinicalTrials.gov NCT05259319) will assess the efficacy and safety of the combination of atezolizumab with tiragolumab and stereotactic body radiation therapy in patients with histologically proven metastatic non-small cell lung cancer, renal cell cancer, bladder cancer, and head and neck cancer previously treated. First part: 2 different schedules of SBRT in association with a fixed dose of atezolizumab and tiragolumab will be investigated only with metastatic non-small cell lung cancer patients (cohort 1). The expansion cohorts phase will be a multicentric, open-label study at the recommended scheme of administration and enroll additional patients with metastatic bladder cancer, renal cell cancer, and head and neck cancer (cohort 2, 3 and 4). Patients will be treated until disease progression, unacceptable toxicity, intercurrent conditions that preclude continuation of treatment, or patient refusal in the absence of progression or intolerance. The primary endpoint of the first phase is the safety of the combination in a sequential or concomitant scheme and to determine the expansion cohorts phase recommended scheme of administration. The primary endpoint of phase II is to evaluate the efficacy of tiragolumab + atezolizumab + SBRT in terms of 6-month PFS (Progression-Free Survival). Ancillary analyses will be performed with peripheral and intratumoral immune biomarker assessments. TRIAL REGISTRATION: This study is registered on ClinicalTrials.gov: NCT05259319, since February 28th, 2022.	bladder
Progress in systemic therapy for advanced-stage urothelial carcinoma.	Despite recent advances, advanced-stage urothelial carcinoma (aUC) remains incurable, with 5-year survival rates of approximately 10%. Platinum-based chemotherapy has a major role as first-line therapy for most patients with aUC. The approval of the anti-PD-L1 antibody avelumab as maintenance therapy for patients without initial disease progression on platinum-based chemotherapy is an important development that has improved the survival outcomes of patients with this disease. Otherwise, the use of first-line immune-checkpoint inhibitors (ICIs) targeting PD-1 or PD-L1 has been restricted to patients who are ineligible for platinum-containing chemotherapy regimens. Other important developments include the FDA-accelerated approval of first-line enfortumab vedotin plus pembrolizumab for patients ineligible to receive cisplatin and the availability of FGFR inhibitors, enfortumab vedotin and sacituzumab govitecan for subsequent lines of therapy. Several research questions remain unaddressed including the lack of adequate biomarkers, how to assign priority to the different treatment options for individual patients and which agents can be effective as monotherapies. The future is promising with the emergence of modalities such as antibody-drug conjugate-like drugs, next-generation ICIs, bispecific antibodies and cellular therapies. In this Review, we summarize the evolution of systemic therapy for patients with aUC and provide insights into the unmet needs.	bladder
Anoikis-associated signatures predict prognosis and immune response in bladder cancer.	Objective: Anoikis is a type of programmed cell death that occurs in normal epithelial and endothelial cells. However, the specific role of anoikis regulators (ANRs) in bladder cancer (BLCA) remains unknown. Therefore, the objective of this study was to find subgroups that could identify different levels of anoikis resistance in BLCA and construct an anoikis scoring system to assess prognosis. Method: By obtaining ANRs from public datasets, subgroups of BLCA with varying degrees of anoikis resistance were identified, and risk was determined. Result: ANRs affects the occurrence and prognosis of BLCA and can be predicted by establishing risk models. Conclusion: The anoikis scoring system and anoikis-associated risk profiles may help develop more effective and personalized treatment strategies for BLCA patients.	bladder
The Prognostic Value of Preoperative Naples Prognostic Score in Upper Tract Urothelial Carcinoma Patients after Radical Nephroureterectomy.	This study aims to determine the prognostic value of preoperative Naples prognostic score (NPS) on survival outcomes in upper tract urothelial carcinoma (UTUC) patients after radical nephroureterectomy (RNU). We conducted a retrospective study about UTUC patients at West China Hospital from January 2015 to June 2019. The X-Tile program was used to identify the optimal cutoff value of NPS. Overall survival (OS), cancer-specific survival (CSS) and progression-free survival (PFS) were the endpoints of interest. Kaplan-Meier curves were used to estimate survival and Cox proportional hazard model was used for risk assessment. A total of 237 UTUC patients after RNU were identified and the threshold of NPS was determined to be 2. Preoperative high-NPS was associated with inferior OS (p = 0.004), CSS (p = 0.002) and PFS (p = 0.008), especially in locally advanced UTUC patients. Preoperative NPS was an independent predictor for OS (HR: 1.78; 95% CI: 1.08, 2.93), CSS (HR: 1.87; 95% CI: 1.11, 3.14) and PFS (HR: 1.60; 95% CI: 1.02, 2.50). The addition of NPS into the predictive model consisting of predictors from multivariate Cox regression resulted in better prediction performance. Preoperative NPS was a novel and reliable predictor for survival in UTUC patients after RNU, and should be further explored.	bladder
